DELTA®-CW4A Board is manufactured from mineral wool bonded together with a high temperature binder. It is thermally efficient, high melt point (over 2000°F.), semi-rigid commercial insulation recommended for fire containment curtain wall systems. DELTA®-CW4A Curtain Wall mineral wool Board installed as part of spandrel wall fire rated assembly prevents fire from breaking through exterior curtain walls for hours. DELTA®-CW4A is available with or without a strong foil-reinforced vapor retarder. Maximum life safety protection against the spread of fire where the floor slab edge meets the curtain wall requires the mechanical installation* of both DELTA®-CW4A and DELTA®- SAFING mineral wool insulations.
